Import Tips
• Verify compounding does not include vulcanizing agents or fillers beyond permitted levels to avoid reclassification to heading 4004 or 4009
• Provide mill test reports confirming unvulcanized state and primary form to CBP for smooth clearance
• Label sheets clearly with material composition to prevent misclassification as finished articles
